MephHeads (LST) organic

Day 45 --> Restart some light LST for the final weeks of Flowering. 🍇 Really intense aromas from stomper n GWK (like sour,sweet grape tannins). ⚠️ In this project we experimented with a super soil like mixture. Biobizz all mix was 65% of the mixture which 1/3 of it was placed on the bottom of the pot and the rest 2/3 was mixed with 35% Canna terra. About 10% perlite was added on the mix and it was sprayed with EM microorganisms (Soil activator). 🏁 The target is a tasty organic flower fed only with tap water and a slow release organic fertilizer(6-3-18) which being applied on the end of the 3rd week and, becomes available to the plants 7 days after. In our case which we transplanted on day 9, we used it on day 30(9+21) from seed. ℹ️ Facts Until the 3rd week plants were growing under LST with no problem (Day 17-19) was when preflower started). In the 4th week development slowed down and initially we though that was due to some drop of temp like midway veg in ➡️ (RQS fem induction). After days were passing and the development of the plants was not satisfying (even though the plants didn't show any symptoms of deficiency or environmental stress) we noticed shiny leaves and dark green colour starting from Stomper#1 which was the smallest plant and was the only one that had some visible burned tips on the leaves. GWK#2 was the only one that did not appear dark green colour or shiny leaves (like SS#1,#2 and GWK#1) but had drooping leaves without having overwatered her or noticing any issues.(Conditions on week 5 and 6 were a bit unstable as the weather got weird and we had high humidity and low temps). Reaching 7th week plant development continues to be average, stems of the most plants became dark red without having low temps inside the tent even though plants look a bit better after they were let to dry a bit more. 🔬 Symptoms 1)Dark shiny leaves 2)Slow growth 3)burn tips 4)Drooping leaves 5) Dark Red stems Matching the pieces of the puzzle we assume that we had NITROGEN TOXICITY and knowing that we do not use any liquid fertilizers it seems that our problem was that our super soil was too "hot" for our baby mephs. If our rooting system of our plants reached the final layer of soil( Biobizz all mix on the bottom of the pot) in the 4th week, it was when it had the highest availability of nitrogen. Availability that seem to be "too hot" for Sour stomper and Grape walker kush in early Flowering. Also in the last weeks we had cold weather so we had an electrical heater on increasing the temp of the room which led to higher temp and transpiration inside the tent.That being said it is likely that due to higher transpiration our plants let higher amount of N to enter the plant and that forced the plants to show us signs of it's toxicity. For a start we let the pots dry to reduce the nitrogen availability and then in Day 45 we water with 6,5 ph tap water + EM microorganisms (700ml each pot). ℹ️ Day 48 : Ideal humidity + temps and the plants have started to drink and eat a lot better the last days. After the second water (700ml) of the week yesterday (D47) with microorganisms only, we find the first signs of deficiency on Sour stomper #2 today. We were expecting this cause our dry fert has only (6-3-18) --> 3 phosphorus (slow release), so our leaves look like having phosphorus and calcium deficiency, we are thinking that the roots locked calcium too with the deficiency of P as these too are collaborating. - So we are going to feed all the plants with organic liquid fert. from Plagron - green sensation PK (9-10) starting with stomper#2. * Every plant in tent has its private watering schedule as the maturity and needs, have changed over the last week. - If the problem continues we'll consider a cal mag solution. * Will be appreciated any comments or same experiences!! Last updated --> Day 49 end of the week.
